ABSTRACT:
A power-on-reset circuit includes first to third first-conductive-type MOSFETs, a second-conductive-type MOSFET, a capacitance, and first to third resistances. In the power-on-reset circuit, whether a reset signal is supplied to an external circuit is determined by threshold voltages of the MOSFETs and independent on the building-up speed of the power supply voltage.
